Hi all,

We're running 389-Directory/1.3.9.0 B2018.304.1940.

Is it possible via ACIs to restrict read/search permission on attributes with a particular value?

My use case is that we have an "isMemberOf" attribute in our directory, and we have some group memberships that are of a sensitive nature. I would like to have all "isMemberOf" attribute values *except* for these sensitive ones readable/searchable to all authenticated user DNs, and the "sensitive" ones only readable/searchable by a particular user DN.

Any ideas? From reading the Red Hat directory server ACI documentation, I can't find a way to do this.

No, I don't think it's possible. Access controls are based on "which attributes you can/can't see", rather than "you can see these attributes except these values within them".

I think that in this case, the possible solutions would be to have a isMemberOfSensitive seperate to the isMemberOf, but that may break many other integrations.

An important question of course, is why are some group memberships sensitive? What is it you are trying to achieve?

Thanks in advance,
